SoCs and kept getting SIGILL, although I was targeting Cortex A7 (and A5,
later), even on A9 and A15.

The glibc will append the content of the CFLAGS variable,
overriding previous flags.
If unset, the CFLAGS variable is not empty, so explicitly set it.
Instead prepend the default CFLAGS flags.

From GCC's standpoint ARC's multilib items are defined by "mcpu" values
which we have quite a few and for all of them might be built optimized
cross-toolchain.
From Glibc's standpoint multilib is just multi-ABI [1] and so very limited
versions are supposed to co-exist (e.g. arc700 & archs).
Here we force Glibc to install libraries in GCC's multilib folder to create
a universal cross-toolchain that has libs optimized for multiple CPU types.
But note we only need to mess with installation paths in case of real
multilib, otherwise we keep default "lib/" paths so that GCC finds default
(the one and only) libs where it expects them to be.
Also here we add a sample which allows to build universal Glibc Linux
toolchain for ARC.

- Disable 2.29 as a choice if host python is older than 3.4

This required some rework of the libc selection, as moxiebox is a layer on
top of another libc - newlib.
Also, moxiebox'es host VM (`sandbox`) needs a libcrypto on the host. We will
not have it if we're cross-compiling a canadian cross. Fortunately, all moxiebox
needs from libcrypto is SHA256, and it already includes a standalone implementation
of SHA256 in its runtime. Provide a little wrapper that allows moxiebox use
that implementation for the host binary, too.
Also, automate collecting/printing the list of all packages in a given category
(e.g. LIBC or COMP_TOOLS), generate a list of all Kconfig symbols for a given
category.

The function is called from a conditional and therefore, the CT_OnError
handler is not invoked on failures. Need to return an error and check

move can fail if it crosses a filesystem, so fall back to 'cp+rm' in
that case.
